Message:

Blogs: Mirror a blog's various comment options to BP's blogmeta.

This commit mirrors the following blog options to BP's blogmeta:

• 'close_comments_for_old_posts'
• 'close_comment_days_old'
• 'thread_comments_depth'

These options will be used later in the new bp_blogs_comments_open()
function to determine whether a blog post's activity item should be
closed from commenting. This is designed to prevent multiple calls
to switch_to_blog().

See #5130

+ * Check if a blog post's activity item should be closed from commenting.
+ *
+ * This mirrors the {@link comments_open()} and {@link _close_comments_for_old_post()}
+ * functions, but for use with the BuddyPress activity stream to be as
+ * lightweight as possible.
+ *
+ * By lightweight, we actually mirror a few of the blog's commenting settings
+ * to blogmeta and checks the values in blogmeta instead.  This is to prevent
+ * multiple {@link switch_to_blog()} calls in the activity stream.
+ *
+ * @since BuddyPress (2.0.0)
+ *
+ * @param object $activity The BP_Activity_Activity object
+ * @return bool
